Periods after miscarriage

Hi everyone. I have a few questions about miscarriages. I had one October 14th at 5 weeks. I’ve already had 2 periods and I’ve ovulated. My body bounced back pretty quickly.

I just got my 2nd period on Saturday. It has been a very light period and lasted only 3 days. I’ve had no cramps and no pain/discomfort. I’m very confused. I usually have a normal 5 day period with normal amount of bleeding.

How are periods supposed to be like after miscarriage? I’ve never been through this and really need advice.
